Symptom evolution in individuals with ongoing symptomatic COVID-19 and post-COVID-19 syndrome after SARS-CoV-2 vaccination versus influenza vaccination.

Background: COVID-19 symptoms may persist beyond acute SARS-CoV-2 infection, as ongoing symptomatic COVID-19 [OSC] (symptom duration 4-12 weeks) and post-COVID syndrome [PCS] (symptom duration ≥12 weeks). Vaccination against SARS-CoV-2 decreases OSC/PCS in individuals subsequently infected with SARS-CoV-2 post-vaccination. Whether vaccination against SARS-CoV-2, or any other vaccinations (such as against influenza) affects symptoms in individuals already experiencing OSC/PCS, more than natural symptom evolution, is unknown.

Whole examination AI estimation of fetal biometrics from 20-week ultrasound scans.

The current approach to fetal anomaly screening is based on biometric measurements derived from individually selected ultrasound images. In this paper, we introduce a paradigm shift that attains human-level performance in biometric measurement by aggregating automatically extracted biometrics from every frame across an entire scan, with no need for operator intervention. We use a neural network to classify each frame of an ultrasound video recording.

Evaluation of a context-aware chatbot using retrieval-augmented generation for answering clinical questions on medication-related osteonecrosis of the jaw.

The potential of large language models (LLMs) in medical applications is significant, and Retrieval-augmented generation (RAG) can address the weaknesses of these models in terms of data transparency and scientific accuracy by incorporating current scientific knowledge into responses. In this study, RAG and GPT-4 by OpenAI were applied to develop GuideGPT, a context aware chatbot integrated with a knowledge database from 449 scientific publications designed to provide answers on the prevention, diagnosis, and treatment of medication-related osteonecrosis of the jaw (MRONJ). A comparison was made with a generic LLM ("PureGPT") across 30 MRONJ-related questions.

Single-cell RNA-seq identifies protracted mouse germline X chromosome reactivation dynamics directed by a PRC2-dependent mechanism.

Female primordial germ cells (PGCs) undergo X chromosome reactivation (XCR) during genome-wide reprogramming. XCR kinetics and dynamics are poorly understood at a molecular level. Here, we apply single-cell RNA sequencing and chromatin profiling on germ cells from F mouse embryos, performing a precise appraisal of XCR spanning from migratory-stage PGCs to gonadal germ cells.

DNA-binding affinity and specificity determine the phenotypic diversity in BCL11B-related disorders.

BCL11B is a Cys2-His2 zinc-finger (C2H2-ZnF) domain-containing, DNA-binding, transcription factor with established roles in the development of various organs and tissues, primarily the immune and nervous systems. BCL11B germline variants have been associated with a variety of developmental syndromes. However, genotype-phenotype correlations along with pathophysiologic mechanisms of selected variants mostly remain elusive.

The Clinical Characteristics and Treatment Outcomes of Mesonephric Tumours of the Uterine Cervix: A Systematic Review and Proposal of Embryologically-Oriented Surgical Resection.

: Cervical mesonephric adenocarcinomas (MNACs) are among the rarest neoplasms of the female genital tract. Unlike the majority of cervical cancers, which are predominantly squamous in origin and strongly associated with HPV seropositivity, MNACs are distinct in both histology and pathophysiology. Despite their unique characteristics, MNACs have historically been managed in parallel with squamous cell carcinomas, resulting in a lack of optimised, evidence-based treatment protocols.

Absorbable Powder Haemostat Use in Minimally Invasive Thoracic Surgery.

: Significant intraoperative and postoperative blood loss are rare but possibly life-threatening complications after lung resection surgery either during open or minimally invasive procedures. Microporous Polysaccharide Haemospheres (ARISTA™AH) have demonstrated time-efficient haemostasis, lower postoperative blood volumes and a lower blood transfusion requirement, without any identified adverse events across other specialities. The primary aim of our study was to evaluate the impact of ARISTA™AH on short-term postoperative outcomes in thoracic surgery.

Recent Advances and Future Directions in Extracorporeal Carbon Dioxide Removal.

Extracorporeal carbon dioxide removal (ECCOR) is an emerging technique designed to reduce carbon dioxide (CO) levels in venous blood while enabling lung-protective ventilation or alleviating the work of breathing. Unlike high-flow extracorporeal membrane oxygenation (ECMO), ECCOR operates at lower blood flows (0.4-1.

Challenging the Binary Classification of Endometrioid Endometrial Adenocarcinoma: The Evaluation of Grade 2 as an Independent Entity Based on Prognostic Characteristics and Recurrence Patterns.

Although grade is a well-recognised prognostic factor for endometrioid endometrial cancer (EEC), in more studies grade 1 (G1) and grade 2 (G2) EEC are combined and compared together with grade 3 (G3) tumours. The aim of our study is to separately investigate the outcomes, prognostic factors and recurrence patterns of G2 EEC and whether the differentiation between G1 and G2 EEC is clinically useful. we retrospectively reviewed 523 patients with EEC treated with primary surgery over a decade (March 2010-January 2020) at Oxford University Hospitals NHS Trust, focusing on those with G2 disease.

Surgical Technique and Perioperative Outcomes of the "Sapienza" Urology Residency Program's Trocar Placement Configuration During Robotic-Assisted Radical Prostatectomy (RARP): A Retrospective, Single-Centre Observational Study Comparing Experienced Attendings vs. Post-Graduate Year I-III Residents as Bedside Assistants.

: Robot-assisted radical prostatectomy (RARP) for the treatment of prostate cancer (PCa) has been standardized over the last 20 years. At our institution, only n = 3 rob arms are used for RARP. In addition, n = 2, 12 mm lap trocars are placed for the bedside assistant symmetrically at the midclavicular lines, which allows for direct pelvic triangulation and greater involvement of the assisting surgeon.

A standardised comparison of chest and percutaneous drainage catheters to evaluate the applicability of the 'French' sizing units.

A variety of medical specialities undertake percutaneous drainage but understanding of device performance outside radiology is often limited. Furthermore, the current catheter sizing using the "French" measurement of outer diameter is unhelpful; it does not reflect the internal diameter and gives no information on flow rate. To illustrate this and to improve catheter selection, notably for chest drainage, we assessed the variation of drain performance under standardised conditions.

The International System for Serous Fluid Cytopathology (TIS) survey in preparation for TIS 2.0.

Introduction: The International System for Serous Fluid Cytopathology (TIS) has gained acceptance and has led to literature validating original concepts and suggesting refinements. In preparation for the second edition of TIS, editors generated a survey to solicit experience with and opinions about TIS.

Materials And Methods: An online survey available from March 8 to June 15, 2024, included 56 questions, offered in 7 languages, related to the practice of serous fluid cytopathology.

Maternal autoimmune systemic connective tissue disease and vasculitis and electrocardiographic findings in the offspring.

Introduction: Maternal autoimmune systemic connective tissue diseases (CTDs) and their related antibodies have been associated with adverse fetal outcomes, including complete heart block. In this study, we assessed the association between maternal CTD or vasculitis and neonatal electrocardiographic (ECG) parameters.

Methods: Our study population was drawn from the Copenhagen Baby Heart Study (CBHS), a prospective, population-based cohort study open to all neonates born in the Copenhagen area.

Age and biologic survival in patients with moderate-to-severe psoriasis: A cohort study from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR).

Background: The current management of psoriasis does not differentiate between young and old patients in selecting the safest and/or most effective biologic.

Objectives: To explore the effect of age at treatment initiation in response to biologics in patients with moderate-to-severe psoriasis in the UK and Eire.

Methods: Data from patients registering to the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) from 2007-2024 on first course of Tumour Necrosis Factor (TNF), interleukin (IL) 12/13, IL-17 and IL-23 inhibitors (i) with at least 6 months' follow-up were included.

Brief Report: Cystatin C Provides Substantially Higher Glomerular Filtration Rate Estimates Than Creatinine in a Subset of Black People With HIV on Current Antiretroviral Regimens.

Background: In African populations, estimated glomerular filtration rate by cystatin C (eGFRcys) is better aligned with gold-standard GFR measurements than eGFR by creatinine (eGFRcr). Moreover, eGFRcys is unaffected by the effects of antiretroviral therapy (ART) on tubular secretion and may thus provide better estimates of GFR in people with HIV on ART.

Setting: Observational cohort study of people of African ancestry living with suppressed HIV RNA on ART in London, United Kingdom.

Impact of cardiovascular magnetic resonance in single ventricle physiology: a narrative review.

Background And Objective: Cardiovascular magnetic resonance (CMR) is a routine cross-sectional imaging modality in adults with congenital heart disease. Developing CMR techniques and the knowledge that CMR is well suited to assess long-term complications and to provide prognostic information for single ventricle (SV) patients makes CMR the ideal assessment tool for this patient cohort. Nevertheless, many of the techniques have not yet been incorporated into day-to-day practice.

Fedratinib combined with ropeginterferon alfa-2b in patients with myelofibrosis (FEDORA): study protocol for a multicentre, open-label, Bayesian phase II trial.

Background: Myelofibrosis (MF) is a clonal haematopoietic disease, with median overall survival for patients with primary MF only 6.5 years. The most frequent gene mutation found in patients is JAK2, causing constitutive activation of the kinase and activation of downstream signalling.

Prospective validation of ORACLE, a clonal expression biomarker associated with survival of patients with lung adenocarcinoma.

Human tumors are diverse in their natural history and response to treatment, which in part results from genetic and transcriptomic heterogeneity. In clinical practice, single-site needle biopsies are used to sample this diversity, but cancer biomarkers may be confounded by spatiogenomic heterogeneity within individual tumors. Here we investigate clonally expressed genes as a solution to the sampling bias problem by analyzing multiregion whole-exome and RNA sequencing data for 450 tumor regions from 184 patients with lung adenocarcinoma in the TRACERx study.

Patient-reported and surgical outcomes of profunda artery perforator (PAP) flap breast reconstructions compared to deep inferior epigastric perforator (DIEP) using BREAST-Q.

Background: Autologous breast reconstruction patients require thorough assessment, with the profunda femoris artery perforator (PAP) flap having become an important autologous reconstruction option alongside the deep inferior epigastric perforator (DIEP) flap. Breast reconstruction impacts patients psychologically, physically and mentally. The BREAST-Q aids in the assessment of patient-reported outcome measures (PROMs).

Neutrophil Extracellular Traps (NETs) as a Potential Target for Anti-Aging: Role of Therapeutic Apheresis.

Neutrophil extracellular traps (NETs) are large structures composed of chromatin, histones and granule-derived proteins released extracellularly by neutrophils. They are generally considered to be a part of the antimicrobial defense strategy, preventing the dissemination of pathogens. However, overproduction of NETs or their ineffective clearance can drive various pathologies, many of which are associated with advanced age and involve uncontrolled inflammation, oxidative, cardiovascular and neurodegenerative stress as underlying mechanisms.

Trends in Ethnic Disparities in Stroke Care and Long-Term Outcomes.

Importance: Reducing the burden of stroke is a public health priority. While higher stroke incidence among ethnic minority populations (defined in the context of this study as individuals who are not White) is well established, reports on ethnic inequalities in care or outcomes are conflicting and often limited to hospital-admitted patients and short-term outcomes.

Objective: To investigate ethnic differences in stroke care and outcomes up to 5 years after stroke and describe temporal trends and contributory factors.
